I had this same error a few days ago, but for a windows xp image. I solved
this issue by creating a soft link, but I'm going to recopy what Brian wrote
to me:

Do you have a public/private key pair in your /etc/vcl/ directory?
>
VCL Keys are configured in vcld.conf with lines that look like these:
IDENTITY_blade_linux=/etc/vcl/bladelinuxkey_id_rsa
IDENTITY_solaris_lab=/etc/vcl/solaris_lab.key
IDENTITY_linux_lab=/etc/vcl/linux_lab.key
IDENTITY_blade_win=/etc/vcl/winxp_blade.key
Usually in my installations I create symbolic links in the /etc/vcl/
directory for things like winxp_blade.key pointing to the /root/.ssh/id_rsa
If you did such a thing for winxp_blade.key, the public key corresponding
to /root/.ssh/id_rsa needs to be placed in the windows vm in your cygwin
area which provides windows with SSH. If the private key is named id_rsa,
usually the public key is in the same directory and named id_rsa.pub
